In the early 90's my family didn't have cable so we had the basic 5 or so channels. I remember flipping through one weekends afternoon I came across a movie I can't forget. There was a couple about to get busy when they think they hear something in the closet, the guy checks and there's is nothing and they kind of laugh it off. As he walks back to them bed something gets his feet from underneath and drags him under. The girl is still on the bed freaking out as a bloody knife comes up thru the mattress a few times. I'm pretty sure she gets stabbed while on the bed still but I clicked off too. As a child one can imagine how this scarred me (as much as I loved being scared by horrors movies too) and I wish I knew knew what it was called as an adult!! No searches haven't helped, hopefully this forum can!!! Thank you!!

I would guess later 80's maybe early, early 90's. I got the feeling it was modern day at the time. Not a Zombie movie or Halloween. Whatever it was seemed just in the house (it wasn't a decrepeted house) and you couldn't see what it was. The other scene I remember was a friend of the girl who was stabbed came to check on her, went into another room and she was killed too. Sorry I can't give a better description, Ive never seen a.movie where someone was stabbed from under the bed thru the mattress but I'm also not a movie expert thanks for any help u can give
